Eurocell is celebrating a 30-year partnership with Carlisle Window Systems, marking three decades of collaboration focused on manufacturing innovation, technical development, and customer-focused window and door solutions across the UK.

Based in Cumbria, Carlisle Window Systems has evolved from a small local installer into one of the region’s leading specialists in PVC-U and aluminium glazing systems. Throughout its growth, the company has manufactured and installed a range of Eurocell systems, including the Logik and Modus platforms, while expanding into new sectors such as timber frame construction.

A key part of the partnership has been Eurocell’s technical and specification support, including U-value calculations, compliance guidance, and product development expertise. Carlisle Window Systems has also integrated Eurocell’s InSite window system into timber frame projects, enabling factory-fitted windows to be installed directly into panels during production. The approach helps accelerate installation programmes while improving weather protection and site efficiency.

Liam Kelly, managing director of Carlisle Window Systems, highlighted the importance of long-term collaboration and technical support in helping the business grow over the past three decades. He also recognised the contribution of Stephen Greaves, Eurocell’s North East technical engineer, for his ongoing expertise and commitment.

The partnership has additionally supported Carlisle’s expansion into aluminium bi-fold doors, sliding systems, and modern window solutions, alongside sustainability initiatives through Eurocell’s recycling and waste take-back schemes.
